Using other types of data stores
Elastic Block Store (EBS) is used to create volumes in an Availability Zone. The volume can only be attached to an EC2 instance in the same Availability Zone. Amazon EBS provides both Solid-State Drive (SSD) and Hard Disk Drive (HDD) types of volumes. For SSD-based volumes, the dominant performance attribute is Input-Output Per Second (IOPS), and for HDD it is throughput, which is generally measured as MiB/s. You can choose between different volume types, such as General Purpose SSD (gp2), Provisioned IOPS SSD (io1), or Throughput Optimized HDD (st1), depending on your requirements. Provisioned IOPS volumes are often used for high-performance workloads, such as deep learning training, where low latency and high throughput are critical. Table 2.1 provides an overview of the different volumes and types:
